摘要： A printer according to the present invention is a so-called tandem-type printer, and has a configuration that a motor gear is directly connected to an M-photoconductor driving gear and an idler gear is directly connected to a Y-photoconductor driving gear and the M-photoconductor driving gear. A diameter of the Y and M photoconductors driving gear, a distance between transfer sections of the Y and M photoconductors, a motor gear input angle, and an idler input angle are set so that an absolute value of a value obtained by subtracting 1 from an ideal amplitude ratio, which indicates a ratio of an ideal amplitude of an eccentric component of the Y-photoconductor driving gear to an actual amplitude of an eccentric component of the M-photoconductor driving gear, is equal to or less than a maximum allowable amplitude ratio.

摘要： A cleaning device includes a cleaning blade disposed in contact with a rotator, a toner collecting section disposed along the rotator and the cleaning blade and includes a groove extending in an axial direction of the rotator, a conveyor disposed in the groove, and an agitator disposed on a side of a rim of the groove. The conveyor rotates to convey the toner in a longitudinal direction of the groove. The agitator vibrates through contact with the conveyor and includes comb-tooth portions lined in a comb shape in the longitudinal direction of the groove, and bent portions, each of which is bent from an end of one of the comb-tooth portions. The comb-tooth portions contact a circumference of the conveyor to vibrate. The bent portions are lined at intervals smaller than intervals on a base side of the comb-tooth portions.
